摘要：To provide an illuminating device and a display device that can perform localdimming control even if their thicknesses are decreased.SOLUTION: An illuminatingdevice comprises: a first light guide plate comprising a first scattering part, a second

scattering part, and a first region in which the first scattering part and the secondscattering part are not arranged; a second light guide plate comprising a third scatteringpart and a fourth scattering part; a first irradiating part for irradiating a first side surfaceof the first light guide plate with light in a first direction; a second irradiating part forirradiating a second side surface opposed to the first side surface with light; a thirdirradiating part for irradiating a third side surface of the second light guide plate withlight in the first direction; and a fourth irradiating part for irradiating a fourth side surfaceopposed to the third side surface with light. The second light guide plate is overlappedwith the first light guide plate in a thickness direction, and the third scattering part andthe fourth scattering part overlap with the first region in the thicknessdirection.SELECTED DRAWING: Figure 3
